I just ordered a Tikka T3X Varmint in 6.5 CM that I will be using as a hunting and 1000 yard target rifle more target oriented than hunting. I have a set of Vortex Precision Matched 30mm rings with a Vortex Diamond Back Tactical 4x16. What scope base would be best for this application? Iam a new Tikka owner and long range shooter so need some help with mounting my scope on my new rifle. Thanks!
